The structures in which human activities are carried out and we are in at any time are reacting with the increasing acid rain and acids caused by different reasons. Building materials lose their chemical and physical properties as a result of reactions with acids. Sille stone, which has quarries in the Sille district of our Konya province, is a building material that has been used since ancient times. The resistance of this building material, which is still preferred in building construction in today's conditions, against acid rain, although it has been encountered in various historical artifacts carried from different cultures and civilizations until today, was discussed in this study. The pH value of rain water varies between 5.6 and 6 and shows acidic properties. It has been observed that the pH value of acid rains fell below 5 and decreased to 3 in some places in the world. Sulfuric acid, nitric acid, carboxylic acid and their mixtures, which are frequently encountered in acid rain, were used in this study. 7x7x7 samples were taken from the stone quarries in Sille district. 1 molar concentration of citric acid was prepared in order to examine the behavior of Sille stone as a result of the reaction of these stones in seasonal acid rains. The samples were kept in natural environment, in water and in acidic environments by varnishing and by without varnishing. In this way, the protected on of stone against acid rains was also analyzed.
